In an alternate timeline, the Declarationists were a faction of Martian colonists who, in the early 23rd century, advocated independence from the government of United Earth. They were opposed by the Human Loyalists, and were finally defeated in 2205. (Star Trek: Myriad Universes novel: A Less Perfect Union)
- The Declarationists presumably took their name from the Fundamental Declarations of the Martian Colonies.
- As few details have been established about the War of Martian Independence as it occurred in the main timeline, it is unclear how different this alternate history is, other than the ultimate outcome.
